[0041] Reference Figure 1-Figure 4 , a gear swing mechanism, comprising:

[0042] The swing frame rotating shaft 4, the swing frame driving member 3, the functional roller 7, the swing frame arm assembly 6 and the reduction gear assembly;

[0043] The swing frame rotation shaft 4 is disposed through the left support member 1 and is rotatably disposed on the right support member 2;

[0044] The fixed end of the swing frame driving member 3 is arranged on the left supporting member 1, and the output end of the swing frame driving member 3 is connected to the swing frame rotating shaft 4; the swing frame driving member 3 can drive the swing frame rotating shaft 4 to rotate circumferentially with the axis of the swing frame rotating shaft 4 as the center;

[0045] The reduction gear assembly is arranged on the swing frame rotating shaft 4 and the swing frame arm assembly 6;

[0046] One end of the group swing arm assembly 6 is rotatably connected to the functional roller 7, and the other end of the group swing arm assembly 6 is connected to the reduction gear assembly.

[0047] The left support member 1 and the right support member 2 are used as components for installing the swing frame driving member 3 and the swing frame rotating shaft 4; the output shaft of the swing frame driving member 3 rotates, driving the swing frame rotating shaft 4 to rotate, thereby controlling the rotation of the swing frame arm assembly 6; due to the provision of a reduction gear assembly, the linear speed of the swing of the functional roller 7 is smaller than the linear speed of the swing frame rotating shaft 4, and the swing amplitude of the swing frame arm assembly can be controlled, thereby adjusting the swing force of the swing frame arm assembly to prevent the functional roller from breaking the film when the film is moving, thereby causing damage to the gear swing frame mechanism.

[0048] Further, the swing arm assembly 6 includes a swing shaft 611, a left swing arm 612 and a right swing arm 622;

[0049] The reduction gear assembly includes a left pinion 51 and a right pinion 52 provided on the swing frame rotating shaft 4, a left swing frame gear 613 provided on the left swing frame arm 612, and a right swing frame gear 623 provided on the right swing frame arm 622;

[0050] The left pinion 51 is meshed with the left swing gear 613; the right pinion 52 is meshed with the right swing gear 623;

[0051] One end of the swing frame shaft 611 is rotatably connected to the left support member 1, and the other end is rotatably connected to the right support member 2;

[0052] The center of the left swing frame gear 613 and the center of the right swing frame gear 623 are both fixedly connected to the swing frame rotating shaft 611;

[0053] The left swing frame arm 612 is fixedly connected to the left swing frame gear 613;

[0054] The right swing arm 622 is fixedly connected to the right swing gear 623 .

[0055] The left pinion 51 meshes with the left swing frame gear 613 for transmission, and the right pinion 52 meshes with the right swing frame gear 623 for transmission. Therefore, by adjusting the rotation range of the swing frame rotating shaft 4, the amplitude of the swing of the swing frame arm assembly 6 driven by the pinion 5 can be controlled, and the swing force of the swing frame arm assembly 6 can be adjusted to prevent the functional roller 7 from breaking the film when the film is moving, thereby causing damage to the gear swing frame mechanism.

[0056] Specifically, it also includes a winding roller 81 disposed between the left support member 1 and the right support member 2 , and both ends of the winding roller 81 are rotatably connected to the left support member 1 and the right support member 2 , respectively.

[0057] More specifically, the functional roller 7 includes a winding roller 71;

[0058] The left swing arm 612 is provided with a left winding roller bearing 11, and the right swing arm 622 is provided with a right winding roller bearing 21; the two ends of the winding roller 71 are respectively connected to the inner rings of the left winding roller bearing 11 and the right winding roller bearing 21;

[0059] The swing frame rotating shaft 4 rotates to drive the pinion 5 and the left swing frame gear 613 and the right swing frame gear 623 to transmit, thereby driving the winding pressure roller 71 to approach / move away from the winding roller 81.

[0060] The winding pressure roller 71 is used to assist the winding roller 81 in winding; when the winding amount of the winding roller 81 increases, the thickness of the film on the winding roller 81 gradually increases along the radial direction of the winding roller 81. At this time, the swing frame rotating shaft 4 is adjusted to drive the left swing frame arm 612 and the right swing frame arm 622 away from the winding roller 81 to support the outermost edge of the film on the winding roller 81, so that the film on the winding roller 81 is rolled tightly to avoid relative sliding between layers of the film.

[0061] More specifically, the functional roller 7 further includes a passing roller 72, and the passing roller 72 is disposed between the winding pressure roller 71 and the swing frame rotating shaft 4;

[0062] The left swing arm 612 is provided with a left roller bearing 12, and the right swing arm 622 is provided with a right roller bearing 22; both ends of the roller 72 are connected to the inner rings of the left roller bearing 12 and the right roller bearing 22 respectively.

[0063] The roller 72 can be used as a film guide for the film.

[0064] More specifically, the winding roller 81 may be an inflatable shaft. Before winding, the inflatable shaft is inflated, and after winding, the inflatable shaft is deflated to quickly remove the film roll on the winding roller 81.

[0065] Reference Figure 3 As shown, further, the thickness of the left pinion 51 is less than the thickness of the left swing gear 613; the thickness of the right pinion 52 is less than the right swing gear 623. The left swing gear 613 and the right swing gear 623 can carry a larger torque than the left pinion 51 and the right pinion 52, thereby improving the load-bearing capacity of the gear swing mechanism.

[0066] Furthermore, the swing frame driving member 3 is a motor, and a fixed end of the motor is arranged on a side of the left supporting member 1 facing away from the right supporting member 2 .

[0067] The ratio of the number of teeth between the left pinion 51 and the left swing gear 613, and between the right pinion 52 and the right swing gear 623 is less than 1.

[0068] This means that the rotation speed of the left swing gear 613 and the right swing gear 623 is lower than the rotation speed of the left pinion 51 and the right pinion 52, thereby improving the swing accuracy of the left swing arm 612 and the right swing arm 622 to avoid breaking the film on the functional roller 7.

[0069] Preferably, the length of the functional roller 7 is 250 mm-2500 mm.

[0070] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
